Upper Verde River Watershed Protection Coalition members have decided to focus on private land for their biomass studies, silt dams, and potential forestry industry because of lengthy waits on archeological surveys required on public lands.
The coalition is working with several agencies and private landowners on a variety of grant-funded projects that require forest restoration work – clearing vegetative overgrowth, including pinion and juniper trees.
The state requires an archeological survey and assessments on its public lands prior to permitting this work; federal lands require the archeological survey and National Environmental Policy Act study.
Doing the same work on private ranchland, however, requires only permission of the owner.
Russ Shumate, Northwest District manager for Arizona Department of Forestry and Fire Management, said at the coalition’s meeting this week the assessment itself isn’t a lengthy process, but finding the money to pay for the study is.
Using private ranches instead of public land may move projects forward, said John Munderloh, Prescott Valley Water Resources manager and Coalition Technical Advisory Committee chair, at the July 26 coalition meeting.
The main thrust of the coalition’s projects involve juniper, which is of low value. The coalition is looking at ways to use the pinion and juniper slash from cleared land in different ways.
One idea is to move the slash into drainage ditches creating silt dams to ease erosion caused by overgrowth of juniper.
The coalition has identified three sections of land north of the Las Vegas Ranch on which to run experiments. A $100,000 Western Forest Leadership Grant will pay for the silt dam projects on one section of state land and two sections of a private ranch.
Another possible use for slash is to create a biomass industry to turn juniper into bio-coal and chips for bio-energy. Drake Cement has conducted co-firing experiments with using pinon-juniper as an…
